To determine the reliability of swept- source optical coherence tomography in cases in which soft contact lenses cannot be removed when acquiring biometric measurements.
Eight subjects were included and only one eye per participant was analyzed. Each eye was measured six times by swept-source optical coherence tomography with the IOLMaster 700 instrument (Carl Zeiss Meditec, Jena, Germany). Axial length, central corneal thickness, anterior chamber depth, lens thickness, and keratometric measurements were evaluated for the naked eye and while wearing soft contact lenses of three different powers (-1.5, -3.0, and +2.0 D).
There were statistically significant changes in axial length, central corneal thickness, anterior chamber depth, and keratometric measurements with soft contact lenses as compared to the naked eye (p<0.001). However, there were no significant differences in lens thickness outcomes between the naked eye and while wearing the three soft contact lenses (p>0.5). The changes in axial length, central corneal thickness, and anterior chamber depth were lens-specific and dependent on the thickness of the lens used.
Sept-source optical coherence tomography based lens thickness measurements while wearing soft contact lenses are comparable to those of the naked eye. However, the thickness and the optical design of the soft contact lens may lead to significant differences in the axial lengh, central corneal thickness, anterior chamber deph, and keratometric measurements.
确定在获取生物测量数据时无法摘除软性隐形眼镜的情况下，扫频光学相干断层扫描的可靠性。
纳入8名受试者，每位参与者仅分析一只眼睛。使用IOLMaster 700仪器（德国耶拿卡尔蔡司医疗技术公司）通过扫频光学相干断层扫描对每只眼睛进行6次测量。对裸眼以及佩戴三种不同屈光度（-1.5、-3.0和+2.0 D）软性隐形眼镜时的眼轴长度、中央角膜厚度、前房深度、晶状体厚度和角膜曲率测量值进行评估。
与裸眼相比，佩戴软性隐形眼镜时眼轴长度、中央角膜厚度、前房深度和角膜曲率测量值有统计学上的显著变化（p<0.001）。然而，裸眼与佩戴三种软性隐形眼镜时的晶状体厚度测量结果无显著差异（p>0.5）。眼轴长度、中央角膜厚度和前房深度的变化具有镜片特异性，且取决于所使用镜片的厚度。
佩戴软性隐形眼镜时基于扫频光学相干断层扫描的晶状体厚度测量结果与裸眼相当。然而，软性隐形眼镜的厚度和光学设计可能导致眼轴长度、中央角膜厚度、前房深度和角膜曲率测量值出现显著差异。
